I just found that my #3 cylinder is running low pressure (110) on my REX....which is causing some issues....so I think I am finally going to get the 2.5L bottom end and start making some real power....My only question is does anyone know where I can get a STI block for fairly cheap?

NASIOC, I have seen them go for around $800, which if you ask me isn't bad at all.

it might not even be your block, your head just might be warped.

I wouldn't think it would be his head, unless he overheated the car badly.

I'm thinking worn rings or maybe a headgasket.

I am sure that it is the rings...

Looks like I am going to go with a STI closed block...should be able to push 25 psi easy with that....or do you all think I should go 2.3L stroker like a buddy of mine wants me to

It's really a toss up there. I'd go with the STi block simply for the higher revving capabilities over the strokers. Do the STi block, head work, cams, and raise the rev limit. That would be sick. :rocks:

Oh yeah, the 25 psi would be nice too. :D :sneaky:

EH....I dont think I am going to raise the rev limit til I get hardened internals...at the moment my No. 1 concern is gettin my Rex back on the road :)....I just need to find out what will work best for me the 2.5L or a stroker....hell I even have some people telling me to just sleeve the EJ20 and fix the rings on the #3....so many choices so little money :)

I personally would go with the 2.5L STi short block.

Definite +1 on the STI shortblock. Or the Cobb 2.2 stroker. Man it is sick....

I just dropped in an STI block. I would say don't sleeve the 2.0 and attempt to keep it. As for the stroker they produce massive torque numbers but you can't rev them as fast, but I personally don't have any personal experience with them.. Here is what I know for sure.. Coupled with the GT35R turbo I noticed a Hugh increase in bottom end.. Even with my fuel map still getting the kinks worked out.. Definitely ditch the 2.0 for the stroker or the 2.5... !Thumbs Up !Thumbs Up

So you dont think fixing the problem and sleeving the EJ20 is worth it?......man I need to win the lotto :)

Well you can sleeve it, but it costs what, 900 for Darton sleeves.. Plus you need rings and other assembly pieces, also you still have to disassemble to a short block anyway, I purchased my STI block from Kerven Subaru for 1,600.. An additional 500 gained me a nice bit of NOTICEABLE bottom end.. Just my suggestion.. But I can honestly say you will NOT regret going to the 2.5.. ;)
